Apple’s iTunes Preview launched in November, letting you preview songs and albums on a web page rather than through the iTunes desktop application. Now Apple has added iTunes App Store pages to iTunes Preview.

Previously, if you visited a direct link to an iPhone/iPod Touch app, you’d be redirected to the iTunes desktop application. Now when you follow those links it’ll still try to launch iTunes but will also see the app information, screenshots and reviews on a web page.

Though it’ll be possible to view iTunes App Store information in the browser, you’ll still need to hop into the iTunes desktop app or grab you iPhone to make buy apps.

Apple’s continuing moves to bring iTunes information to the web also suggests that rumours of a cloud-computing-based iTunes.com web service could be right on the money.
